You’d think archaeologists would have found all the pyramids of Africa by now, but two recent discoveries show there’s a lot more discovering to be done.

A team of archaeologists working in Luxor, Egypt, have just announced they’ve discovered the pyramid of Khay, a powerful vizier of the Pharaoh Ramses II (ruled 1279-1212 B.C.). The pyramid was made of mudbrick and originally stood 49 feet high.

In the seventh and eighth century A.D. it was dismantled and turned into a Coptic Christian hermitage. Hieroglyphic writing on the surviving bricks told the archaeologists to whom the pyramid belonged.

Earlier this month, archaeologists announced they had found the bases of at least 35 broken pyramids at the site of Sedeinga in Sudan. They’re about 2,000 years old and belong to the kingdom of Kush, which lasted from c.1000 B.C. to 350 A.D. before finally being conquered by the Empire of Axum in Ethiopia. For almost a hundred years from 747-656 B.C., the Kushites ruled Egypt as the 25th dynasty.

The Sedeinga pyramids really just pyramid-shaped tombs. The largest measures 22 feet to a side, while the smallest is only 30 inches to a side. Others in Sudan, such as those at Meroë, are much more grandiose. Those at the pyramid field at Nuri, shown here courtesy Vít Hassan, are up to 150 feet tall.

So how could these pyramids go missing? Well, most pyramids were much smaller than the famous ones at Giza and Saqqara that we always see pictures of. Shifting sands and erosion helped hide them. In the case of the Sedeinga tombs, later people took stones from them to build other structures.

Even some sizable pyramids have all but disappeared because they were made of inferior materials. Some of the last pyramids of Egypt are barely visible today because of shoddy workmanship or having been made with mudbrick instead of stone.

The boat was meant to take the Pharaoh Den to the afterlife and was buried in the northeast of the Giza Plateau, site of the famous (and later) pyramids. Den was a ruler of Ancient Egypt’s poorly understood First Dynasty, which saw the unification of Egypt and its development as a major civilization. Den, shown here smiting his enemies in this image courtesy CaptMondo, was the first to use the title “King of Lower and Upper Egypt.” He ruled for 42 years and was famed for his organization of the state. His tomb at Abydos, shown below in this Wikimedia Commons image, is one of the finest of the era.

The French team that made the discovery hope to restore the boat in time to put it on display at the National Museum of Egyptian Civilization when it opens next year.

Egyptologists have made a stunning discovery at the famous temple of Luxor: an inscription naming a previously unknown Egyptian pharaoh.

A French team restoring a temple of Amon Ra found hieroglyphs bearing the name “Nekht In Ra.” The inscription dates to the 17th dynasty, a relatively little-known dynasty from a murky period in Egyptian history.

The mysterious dynasty was the last of the Second Intermediate Period, a time when northern Egypt was ruled by Semitic invaders called the Hyksos and the rest of Egypt had fragmented into various factions. The 17th dynasty dated from around 1585 to 1550 BC and had their capital at Thebes, next to Luxor. Most of the dates of its rulers are not known for certain and in many cases it’s not even known how long they ruled or who was related to whom. Thus the discovery of a “new” pharaoh, while important, doesn’t come as a huge surprise.

It’s unclear just how Nekht In Ra fits into the king list of the ten previously known 17th dynasty pharaohs. The Egyptian Ministry of Antiquities has called for further excavation at the discovery site to find more pieces to the puzzle.

While the 17th dynasty is obscure, it was hugely important to Egyptian history because the last two pharaohs waged war on the Hyksos and eventually defeated them, although both pharaohs appear to have died in battle. The 18th dynasty marked the beginning of the New Kingdom, a flowering of Egyptian culture and power that lasted five centuries.

Several interesting items survive from the 17th dynasty and are now on display. Check out the gallery for a sample.

The Egyptian Minister of State for Antiquities Mohamed Ibrahim has announced that the Avenue of Sphinxes in Luxor will reopen in March after a long period of restoration.

Luxor is a sprawling complex of temples and one of the greatest monuments of the ancient world. The Avenue of Sphinxes is a long road stretching 2.7 kilometers flanked by hundreds of sphinxes. It was built by the Pharaoh Nectanebo I (ruled 380-362 BC) to replace and earlier one built by Queen Hatshepsut (ruled 1502-1482 BC).

While some stretches of the avenue have always been visible, much of it was buried or destroyed over the centuries. Now the entire length is being restored as part of an ongoing project to improve the entire site.

The opening is planned to coincide with next year’s Berlin International Tourism Market. Egypt is anxious to draw tourists back to the country after the recent political instability. Considering the current protests in Cairo, the government has a lot of work to do before March.

German archaeologists studying a skin cream once owned by Queen Hatshepsut have found evidence that the female pharaoh may have accidentally poisoned herself.

The tiny bottle, which has an inscription saying it was owned by Hatshepsut, was still partially filled with a substance that the archaeologists subjected to chemical analysis. It included nutmeg and palm oils, commonly used to soothe skin irritations. It also included benzopyrene, which smells nice but is highly carcinogenic. It’s found in burnt substances such as pitch, coal tar, cigarette smoke, and burnt foods such as barbeque and coffee. Keep that in mind this Labor Day Weekend.

In contrast to the idealized statue of Hatshepsut shown here, her mummy revealed that she was obese, had liver cancer, and probably suffered from diabetes.

Hatshepsut’s rule saw two decades of peace and ambitious trade expeditions as far as Puntland, which was probably in the modern unrecognized state of the same name. Her modern-looking temple at Deir el Bahri is one of Egypt´s most stunning attractions. You can reach it by bus, or if you’re feeling adventurous you can take a mountain path from the Valley of the Kings, which leads you to a cliff overlooking the temple before sloping down past the tombs of its builders and to the temple itself. I did this one August, which is not the best time. That was probably as bad for my skin as Hatshepsut’s skin cream.
